ASVP | Air Sampling Vacuum Pump
Our Air Sampling Vacuum Pump (ASVP) is engineered to deliver the optimal flow of ambient air for sampling in dry rooms, cleanrooms, or environmental chambers. This unit ensures precise moisture measurements by providing the necessary airflow to our range of portable dewpoint hygrometers.
Designed for versatility and safety, the ASVP supports accurate moisture measurement across various applications, including dry or clean rooms, glove boxes, environmental chambers, product drying, and cool stores — providing an optimal flow of ambient air to the SADPmini2, SADPmini2-L or SADPmini2-Ex portable dewpoint hygrometers.
Offering an optimal flow rate of 2 litres per minute for accurate sampling, the ASVP is user-friendly with an easy-to-read colour display, a simple four-button navigation interface, a motion detection feature for usage alerts, a lockable keypad to prevent tampering and a smooth finish for easy decontamination. The ASVP is certified as intrinsically safe for operation in flammable atmospheres, allowing it to be used in potentially explosive zones — when combined with the SADPmini2-Ex portable dewpoint hygrometer.

SADPmini2-Ex Portable Dewpoint Hygrometer
Certified intrinsically safe to IECEx, ATEX, and cULus standards, our SADPmini2-Ex portable dewpoint hygrometer combines safety and performance — suitable for use in hazardous areas.
The SADPmini2-Ex advanced portable hygrometer is ideal for precise trace moisture measurement in hazardous environments and with potentially explosive gases — with logging capability and Bluetooth connectivity to our portable printer. The full-colour LCD shows multiple engineering units simultaneously, along with real-time graphing and screenshot features.
Market leading sensing technology combined with a unique desiccant head assembly ensures unparalleled speed of response and trace moisture detection. As a result, the SADPmini2-Ex offers exceptional sensitivity — accurate to ±2 °C (±3.6 °F) dewpoint — and fast, consistent operation with minimal air/gas usage.
SADPmini2-L Advanced Portable Hygrometer
Our SADPmini2-L advanced portable hygrometer is ideal for precise trace moisture measurement in industrial gases and compressed air — with logging capability and Bluetooth connectivity to our portable printer.
Market-leading sensing technology combined with a unique desiccant head assembly ensures unparalleled speed of response. As a result, the SADPmini2-L offers exceptional sensitivity, accurate to ±2 °C (±3.6 °F) dewpoint — and fast, consistent operation with minimal air/gas usage.
The SADPmini2-L is designed for ease of use and reliability in demanding environments, with a full-colour LCD display showing multiple engineering units simultaneously, along with real-time graphing and screenshot features and advanced data logging and connectivity to accurately record and store trace moisture measurement data for later analysis.
DS1500 Display
A sophisticated, panel mount, single-channel display, designed to enhance continuous trace moisture measurement in various gases and dry compressed air systems — when used with a compatible dewpoint transmitter.
The DS1500 incorporates RS485 and MODBUS (RTU) capabilities to facilitate remote interrogation and comprehensive communication with the AMT, AMT-Ex and PDT dewpoint transmitters, for continuous trace moisture measurement across a range of applications.
Factory configured to user specifications, the DS1500 can display measurements in °C dewpoint, °F dewpoint, ppm(V), ppb(V), g/m³, or lb/MMSCF on a large, six-digit, red LED display, providing clear and immediate data readouts. It offers Process Variable (PV) retransmission in 0-20 or 4-20 mA and is user-configurable to input pressure for pressure dewpoint conversion — offering a solution that is as versatile as it is reliable.
